I have several cisco kit with serious outdated SW on them.įrom Nexus, ASA’s, Catalyst switches, etc. With that information, send TAC Support an e-mail including the output of the “show ver” command and the list of vulnerabilities and you will be sent a one-off link to obtain the latest IOS image for your device, free of charge. Paste in the output of the “ show ver” command and you’ll be presented with a list of vulnerabilities affecting your device. Great! So we can probably get free updates if they fix a security issue, so what next? Head over to a handy on-line Cisco tool to identify what vulnerabilities are present in the version of IOS you’re running. To verify their entitlement, individuals who contact the TAC should have available the URL of the Cisco document that is offering the update. If Cisco has offered a free software update to address a specific issue, noncontract customers who are eligible for the update may obtain it by contacting the Cisco TAC using any of the means described in the Contact Summary section of this document.

There’s a way to legally obtain an updated version that many people over look, security updates.Īs it stands, CISCO’s security vulnerability policy states that (emphasis mine):Īs a special customer service, and to improve the overall security of the Internet, Cisco may offer customers free of charge software updates to address security problems. It’s safe to say you’ll want to avoid resorting to piracy, Perhaps you don’t want to spend the money on a SMARTnet subscription. Lets say you have a Cisco router that’s running an out of date IOS version and want to get a more recent image.
